Electrostatic discharge (ESD) events can cause arcing that damages sensitive electronics, especially in compact devices like cell phones. In previous tutorials, we went through the air ESD into a calibration target and air ESD into PCB tutorials available within Charge Plus. In this blog, we visualize primary and secondary arcing on a simplified cell phone model using ParaView.
Overview
ParaView is an open-source visualization tool designed for exploring large 3D simulation datasets. In this example, we use it to visualize the air conductivity results of the ESD gun discharging into a simplified cell phone model, shown below.
The 3D model
For this example, the source voltage was set to 25 kV. The source voltage and the ESD waveform are shown below.
The source voltage
The ESD waveform
The air conductivity results are shown below. The simulation reveals an arc from the ESD gun to the PCB, a secondary arc between the ESD gun and a nearby board, and an additional arc between that board and the PCB.
The video below walks through the steps in detail for importing the results into ParaView, and the model is available in the downloadable resources.
